How to confirm Access Database Engine (ACE Driver) is installed on Database Server

Follow these steps to verify Access Database Engine (ACE Driver) installation;

Double check to make sure you did install the x64 version of Microsoft Access Database Engine here –  Please note that only one version x64 –OR– x86 can be installed, not both.

Here is a SQL Server x64 server with the Microsoft Access Database Engine x32 installed – see it does not show up.

Here is the same server with the Microsoft Access Database Engine x64 installed – see how it shows up.

I do not know of a query to get a list of the providers – however if you look in the registry at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10.MSSQLSERVER\Providers and check for the key Microsoft.ACE.OLEDB.12.0

This will tell you that it is installed.  If you have a 32-bit version installed on a 64-bit box you would need to look under the Wow6432Node, that key would be HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server\MSSQL10.MSSQLSERVER\Providers.

You would have to make sure that both SQL Server and the ODBC/OLEDB driver are the same bitwise either both x64 or x32.
